Recent work proposes using world models to generate controlled virtual environments in which AI agents can be tested before deployment to ensure their reliability and safety. However, accurate world m...

Conway's Game of Life (GOL) is a cellular automaton that has captured the interest of hobbyists and mathematicians alike for more than 50 years. The Game of Life is Turing complete, and people have be...

The first part of this trilogy is devoted to discussing the difference between model and simulation, one of the cornerstones for understanding relational biology. How true is it that Robert Rosen deni...

How a group of Silicon Valley math prodigies, AI researchers and internet burnouts descended into an alleged violent cult

The internal model principle, originally proposed in the theory of control of linear systems, nowadays represents a more general class of results in control theory and cybernetics. The central claim o...

Elon Musk claims to have found rampant fraud in the Social Security Administration. There's a much simpler explanation.

Process theories provide a powerful framework for describing compositional structures across diverse fields, from quantum mechanics to computational linguistics. Traditionally, they have been formaliz...

Relating microscopic interactions to macroscopic observables is a central challenge in the study of complex systems. Addressing this question requires understanding both pairwise and higher-order inte...

We introduce effectful Mealy machines - a general notion of Mealy machine with global effects - and give them semantics in terms of both bisimilarity and traces. Bisimilarity of effectful Mealy machin...

While we encourage people to use AI systems during their role to help them work faster and more effectively, please do not use AI assistants during the application process. We …

An organization developing math benchmarks for AI didn’t disclose that it had received funding from OpenAI until relatively recently, drawing allegations of impropriety from some in the AI community. Epoch AI, a nonprofit primarily funded by Open…

CCL: Categorical Configuration Language

"Pasta alla Cacio e pepe" is a traditional Italian dish made with pasta, pecorino cheese, and pepper. Despite its simple ingredient list, achieving the perfect texture and creaminess of the sauce can ...

Former Black Panthers fear the FBI is still keeping tabs on them decades after COINTELPRO. In at least one case, they were right.
